Paper Abstract

Differential optical absorption spectroscopy (DOAS) gas-analyzer was successfully tested. Ultraviolet light emitting diodes and high pressure Xe arc lamp were employed as a light sources. Recent developments in fibre-coupling telescope technology and the availability of UV LEDs allowed us to construct a portable instrument. The DOAS system consisted of a coaxial telescope, a spectrometer, and retroreflector. Gas analyzer spectral data bank includes more than 40 molecules absorbed in UV spectral region. Minimally detected concentration is the unit of ppb on paths up to 500 m. The results of the field test measurements of pollutants in Tomsk are presented
